LOS ANGELES (Reuters) - Rob Grill, the longtime lead singer for rock band The Grass Roots, has died at age 67 from complications of a stroke, his agent said on Tuesday. Grill died on Monday at a hospice outside Orlando, Florida, with his wife, Nancy, at his side, said his agent Howie Silverman of Paradise Artists. Grill joined The Grass Roots in 1967, soon after it was created by songwriters Steve Barri and PF Sloan, and soon scored a hit with the song Lets Live for Today. The bands other hits with Grill as lead singer included Midnight Confessions and Temptation Eyes. The Grass Roots has cycled through many band members over the years, but Grill was a constant force in the group as both a musician and songwriter.
